22. Consider 3 resistors with resistances 1.2 x 102 Ω, 2.5 k Ω, and 3.6 k Ω.
a) What would be their resistance, RS, in kilohms, if they were connected in series?
b) What would be their resistance, RP, in ohms, if they were connected in parallel?
Solution:
Given data:
Values for three resistors are
R1 = 1.2 102 = 122.4
R2 = 2.5 k
R3 = 3.6 k
Total parallel resistance :
RP =
= 113.02 = 0.11302 k
Total series resistance:
RS =
= 122.4 + 2.5 k + 3.6k = 6222.4 = 6.2224 k
